ACTION: Final rule. AGENCY: This regulation establishes an exemption from the requirement of a tolerance for residues of paraffin waxes and hydrocarbon waxes, carboxypolymethylene resin, and paraffin waxes and hydrocarbon, oxidized, lithium salts when used as inert ingredients (flow aid, surface protectant, binder, carrier, coating agent or adjuvant) on growing crops and raw agricultural commodities pre- and postharvest, applied in/on animals, and in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. Spring Regulatory Sciences, on behalf of Sasol Chemicals (USA) LLC, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of paraffin waxes and hydrocarbon waxes, carboxypolymethylene resin oxidized paraffin wax, and paraffin waxes and hydrocarbon, oxidized, lithium salts, when used in accordance with the terms of those exemptions. DATES: This regulation is effective March 17, 2023.

Petition for Exemption In the Federal Register of March 22, 2021 (86 FR 15164, FRL–10021–44), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 346a, announcing the filing of a pesticide petition (PP IN–11450) by Spring Regulatory Sciences, 6620 Cypresswood Dr., Suite 250, Spring, TX 77379, on behalf of Sasol Chemicals (USA) LLC, 12120 Wickchester Lane, Houston, TX 77224. The petition requested that 40 CFR be amended by establishing an exemption from the requirement of a tolerance for residues of paraffin waxes and hydrocarbon waxes (CAS Reg. No. 8002–74–2); carboxypolymethylene resin (CAS Reg. No. 68153–22–0) (also known as oxidized paraffin wax); and paraffin waxes and hydrocarbon, oxidized, lithium salts (CAS Reg. No. 68649–48–9), when used as an inert ingredient (flow aid, surface protectant, binder, carrier, coating agent or adjuvant) in pesticide formulations applied to growing crops and raw agricultural commodities pre- and postharvest under 40 CFR 180.910, applied in/on animals under 40 CFR 180.930, and in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing E:\FR\FM\17MRR1.SGM 17MRR1 16380 Federal Register / Vol. 88, No. 52 / Friday, March 17, 2023 / Rules and Regulations equipment, and food-processing equipment and utensils under 40 CFR 180.940(a). For ease of reading, all three chemicals are referred to collectively as paraffin waxes in the following sections. There were no comments received in response to the notice of filing. lotter on DSK11XQN23PROD with RULES1 III. Inert Ingredient Definition Inert ingredients are all ingredients that are not active ingredients as defined in 40 CFR 153.125 and include, but are not limited to, the following types of ingredients (except when they have a pesticidal efficacy of their own): Solvents such as alcohols and hydrocarbons; surfactants such as polyoxyethylene polymers and fatty acids; carriers such as clay and diatomaceous earth; thickeners such as carrageenan and modified cellulose; wetting, spreading, and dispersing agents; propellants in aerosol dispensers; microencapsulating agents; and emulsifiers. The term ‘‘inert’’ is not intended to imply nontoxicity; the ingredient may or may not be chemically active. Generally, EPA has exempted inert ingredients from the requirement of a tolerance based on the low toxicity of the individual inert ingredients. IV. Aggregate Risk Assessment and Determination of Safety Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an exemption from the requirement for a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is ‘‘safe.’’ Section 408(c)(2)(A)(ii) of FFDCA defines ‘‘safe’’ to mean that ‘‘there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.’’ This includes exposure through drinking water and in residential settings but does not include occupational exposure. When making a safety determination for an exemption for the requirement of a tolerance FFDCA section 408(c)(2)(B) directs EPA to consider the considerations in section 408(b)(2)(C) and (D). Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to ‘‘ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .’’ Section 408(b)(2)(D) lists other factors for EPA consideration making safety determinations, e.g., the validity, VerDate Sep<11>2014 15:41 Mar 16, 2023 Jkt 259001 completeness, and reliability of available data, nature of toxic effects, available information concerning the cumulative effects of the pesticide chemical and other substances with a common mechanism of toxicity, and available information concerning aggregate exposure levels to the pesticide chemical and other related substances, among others. EPA establishes exemptions from the requirement of a tolerance only in those cases where it can be clearly demonstrated that the risks from aggregate exposure to pesticide chemical residues under reasonably foreseeable circumstances will pose no harm to human health. In order to determine the risks from aggregate exposure to pesticide inert ingredients, the Agency considers the toxicity of the inert in conjunction with possible exposure to residues of the inert ingredient through food, drinking water, and through other exposures that occur as a result of pesticide use in residential settings. If EPA is able to determine that a finite tolerance is not necessary to ensure that there is a reasonable certainty that no harm will result from aggregate exposure to the inert ingredient, an exemption from the requirement of a tolerance may be established. Consistent with FFDCA section 408(c)(2)(A), and the factors specified in FFDCA section 408(c)(2)(B), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for paraffin waxes including exposure resulting from the exemption established by this action. EPA’s assessment of exposures and risks associated with paraffin waxes follows. A. Toxicological Profile EPA has evaluated the available toxicity data and considered their validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. Specific information on the studies received and the nature of the adverse effects caused by paraffin waxes as well as the noobserved-adverse-effect-level (NOAEL) and the lowest-observed-adverse-effectlevel (LOAEL) from the toxicity studies are discussed in this unit. Paraffin waxes exhibit low levels of acute toxicity via the oral, and dermal routes of exposure and they are PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 anticipated to have low acute toxicity via the inhalation route. Paraffin waxes are non-irritating to the eye or skin, and they are not dermal sensitizers. The repeated-dose toxicity for paraffin waxes is low. No adverse effects were observed in a 90-day oral rat study or in a developmental toxicity study in rats up to the limit dose. No acceptable oral chronic or carcinogenicity studies are available for paraffin waxes. However, there is low concern for genotoxicity or mutagenicity based on negative results in mammalian and bacterial genotoxicity tests. No evidence of neurotoxicity was observed in the neurotoxicity screening performed in the 90-day oral rat study and no evidence of immunotoxicity was seen in the available studies. B. Toxicological Points of Departure/ Levels of Concern Once a pesticide’s toxicological profile is determined, EPA identifies toxicological points of departure (POD) and levels of concern to use in evaluating the risk posed by human exposure to the pesticide. For hazards that have a threshold below which there is no appreciable risk, the toxicological POD is used as the basis for derivation of reference values for risk assessment. PODs are developed based on a careful analysis of the doses in each toxicological study to determine the dose at which no adverse effects are observed (the NOAEL) and the lowest dose at which adverse effects of concern are identified (the LOAEL). Uncertainty/ safety factors are used in conjunction with the POD to calculate a safe exposure level—generally referred to as a population-adjusted dose (PAD) or a reference dose (RfD)—and a safe margin of exposure (MOE). For non-threshold risks, the Agency assumes that any amount of exposure will lead to some degree of risk. Thus, the Agency estimates risk in terms of the probability of an occurrence of the adverse effect expected in a lifetime. For more information on the general principles EPA uses in risk characterization and a complete description of the risk assessment process, see https:// www.epa.gov/pesticide-science-andassessing-pesticide-risks/overview-riskassessment-pesticide-program. The hazard profile of paraffin waxes is adequately defined. Overall, paraffin waxes are of low acute, subchronic, and developmental/reproductive toxicity. No systemic toxicity is observed up to 1,000 mg/kg/day. Since signs of toxicity were not observed, no toxicological endpoints of concern or PODs were identified. Therefore, a qualitative risk E:\FR\FM\17MRR1.SGM 17MRR1 Federal Register / Vol. 88, No. 52 / Friday, March 17, 2023 / Rules and Regulations assessment for paraffin waxes can be performed. lotter on DSK11XQN23PROD with RULES1 C. Exposure Assessment 1. Dietary exposure. In evaluating dietary exposure to paraffin waxes, EPA considered exposure under the proposed exemption from the requirement of a tolerance. EPA assessed dietary exposures from paraffin waxes in food and drinking water as follows: Dietary exposure (food and drinking water) to paraffin waxes may occur from foods containing these inert ingredients and from non-pesticidal uses (e.g., cosmetics and personal care). However, no toxicological endpoints of concern were selected, and therefore, a quantitative dietary exposure assessment for paraffin waxes was not conducted. 2. From non-dietary exposure. The term ‘‘residential exposure’’ is used in this document to refer to nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Although the current and proposed uses of paraffin waxes can result in residential exposures, no toxicological endpoints were selected, and therefore, it is not necessary to conduct a quantitative assessment of residential exposures and risks. 3. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider ‘‘available information’’ concerning the cumulative effects of a particular pesticide’s residues and ‘‘other substances that have a common mechanism of toxicity.’’ Based on the lack of toxicity in the available database, EPA has not found paraffin waxes to share a common mechanism of toxicity with any other substances, and paraffin waxes do not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance exemption, therefore, EPA has assumed that the paraffin waxes in this petition do not have a common mechanism of toxicity with other substances. For information regarding EPA’s efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA’s website at https:// www.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides. VerDate Sep<11>2014 15:41 Mar 16, 2023 Jkt 259001 D. Additional Safety Factor for the Protection of Infants and Children Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an additional tenfold (10X) margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the database on toxicity and exposure unless EPA determines based on reliable data that a different margin of safety will be safe for infants and children. This additional margin of safety is commonly referred to as the Food Quality Protection Act (FQPA) Safety Factor (SF). In applying this provision, EPA either retains the default value of 10X, or uses a different additional safety factor when reliable data available to EPA support the choice of a different factor. Based on an assessment of paraffin waxes, EPA has concluded that there are no toxicological endpoints of concern for the U.S. population, including infants and children. Because there are no threshold effects associated with paraffin waxes, EPA conducted a qualitative assessment. As part of that assessment, the Agency did not use safety factors for assessing risk, and no additional safety factor is needed for assessing risk to infants and children. E. Aggregate Risks and Determination of Safety Because no toxicological endpoints of concern were identified, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to paraffin wax residues. V. Other Considerations Analytical Enforcement Methodology An analytical method is not required for enforcement purposes since the Agency is establishing an exemption from the requirement of a tolerance without any numerical limitation. VI. Conclusions Therefore, an exemption from the requirement of a tolerance is established for residues of paraffin waxes, paraffin waxes and hydrocarbon waxes (CAS Reg. No. 8002–74–2); carboxypolymethylene resin (CAS Reg. No. 68153–22–0); and paraffin waxes and hydrocarbon, oxidized, lithium salts (CAS Reg. No. 68649–48–9) when used as inert ingredients (flow aid, surface protectant, binder, carrier, coating agent or adjuvant) in pesticide formulations applied to growing crops and raw agricultural commodities preand post-harvest under 40 CFR 180.910, PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 16381 applied in/on animals under 40 CFR 180.930, and in antimicrobial formulations applied to food-contact surfaces in public eating places, dairyprocessing equipment, and foodprocessing equipment and utensils under 40 CFR 180.940(a). VII. Statutory and Executive Order Reviews This action establishes exemptions from the requirement of a tolerance under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ‘‘Regulatory Planning and Review’’ (58 FR 51735, October 4, 1993). Because this action has been exempted from review under Executive Order 12866, this action is not subject to Executive Order 13211, entitled ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997). This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations’’ (59 FR 7629, February 16, 1994). Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the exemptions in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply. This action directly regulates growers, food processors, food handlers, and food retailers, not States or Tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or Tribal Governments, on the relationship between the National Government and the States or Tribal Governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian Tribes. Thus, the Agency has determined that Executive Order 13132, E:\FR\FM\17MRR1.SGM 17MRR1 16382 Federal Register / Vol. 88, No. 52 / Friday, March 17, 2023 / Rules and Regulations entitled ‘‘Federalism’’ (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled ‘‘Consultation and Coordination with Indian Tribal Governments’’ (65 FR 67249, November 9, 2000) do not apply to this action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.). This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note). VIII. Congressional Review Act Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2). List of Subjects in 40 CFR Part 180 PART 180—TOLERANCES AND EXEMPTIONS FOR PESTICIDE CHEMICAL RESIDUES IN FOOD 1.

Paraffin Waxes and Hydrocarbon Waxes, Carboxypolymethylene Resin, 
and Paraffin Waxes and Hydrocarbon, Oxidized, Lithium Salts in 
Pesticide Formulations; Tolerance Exemption

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes an exemption from the requirement 
of a tolerance for residues of paraffin waxes and hydrocarbon waxes, 
carboxypolymethylene resin, and paraffin waxes and hydrocarbon, 
oxidized, lithium salts when used as inert ingredients (flow aid, 
surface protectant, binder, carrier, coating agent or adjuvant) on 
growing crops and raw agricultural commodities pre- and post-harvest, 
applied in/on animals, and in antimicrobial formulations applied to 
food-contact surfaces in public eating places, dairy-processing 
equipment, and food-processing equipment and utensils. Spring 
Regulatory Sciences, on behalf of Sasol Chemicals (USA) LLC, submitted 
a petition to EPA under the Federal Food, Drug, and Cosmetic Act 
(FFDCA), requesting establishment of an exemption from the requirement 
of a tolerance. This regulation eliminates the need to establish a 
maximum permissible level for residues of paraffin waxes and 
hydrocarbon waxes, carboxypolymethylene resin oxidized paraffin wax, 
and paraffin waxes and hydrocarbon, oxidized, lithium salts, when used 
in accordance with the terms of those exemptions.

DATES: This regulation is effective March 17, 2023. Objections and 
requests for hearings must be received on or before May 16, 2023 and 
must be filed in accordance with the instructions provided in 40 CFR 
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Petition for Exemption

    In the Federal Register of March 22, 2021 (86 FR 15164, FRL-10021-
44), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (PP IN-11450) by 
Spring Regulatory Sciences, 6620 Cypresswood Dr., Suite 250, Spring, TX 
77379, on behalf of Sasol Chemicals (USA) LLC, 12120 Wickchester Lane, 
Houston, TX 77224. The petition requested that 40 CFR be amended by 
establishing an exemption from the requirement of a tolerance for 
residues of paraffin waxes and hydrocarbon waxes (CAS Reg. No. 8002-74-
2); carboxypolymethylene resin (CAS Reg. No. 68153-22-0) (also known as 
oxidized paraffin wax); and paraffin waxes and hydrocarbon, oxidized, 
lithium salts (CAS Reg. No. 68649-48-9), when used as an inert 
ingredient (flow aid, surface protectant, binder, carrier, coating 
agent or adjuvant) in pesticide formulations applied to growing crops 
and raw agricultural commodities pre- and post-harvest under 40 CFR 
180.910, applied in/on animals under 40 CFR 180.930, and in 
antimicrobial formulations applied to food-contact surfaces in public 
eating places, dairy-processing

[[Page 16380]]

equipment, and food-processing equipment and utensils under 40 CFR 
180.940(a). For ease of reading, all three chemicals are referred to 
collectively as paraffin waxes in the following sections. There were no 
comments received in response to the notice of filing.

III. Inert Ingredient Definition

    Inert ingredients are all ingredients that are not active 
ingredients as defined in 40 CFR 153.125 and include, but are not 
limited to, the following types of ingredients (except when they have a 
pesticidal efficacy of their own): Solvents such as alcohols and 
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty 
acids; carriers such as clay and diatomaceous earth; thickeners such as 
carrageenan and modified cellulose; wetting, spreading, and dispersing 
agents; propellants in aerosol dispensers; microencapsulating agents; 
and emulsifiers. The term ``inert'' is not intended to imply 
nontoxicity; the ingredient may or may not be chemically active. 
Generally, EPA has exempted inert ingredients from the requirement of a 
tolerance based on the low toxicity of the individual inert 
ingredients.

IV. Aggregate Risk Assessment and Determination of Safety

    Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an 
exemption from the requirement for a tolerance (the legal limit for a 
pesticide chemical residue in or on a food) only if EPA determines that 
the tolerance is ``safe.'' Section 408(c)(2)(A)(ii) of FFDCA defines 
``safe'' to mean that ``there is a reasonable certainty that no harm 
will result from aggregate exposure to the pesticide chemical residue, 
including all anticipated dietary exposures and all other exposures for 
which there is reliable information.'' This includes exposure through 
drinking water and in residential settings but does not include 
occupational exposure. When making a safety determination for an 
exemption for the requirement of a tolerance FFDCA section 408(c)(2)(B) 
directs EPA to consider the considerations in section 408(b)(2)(C) and 
(D). Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue. . . 
.'' Section 408(b)(2)(D) lists other factors for EPA consideration 
making safety determinations, e.g., the validity, completeness, and 
reliability of available data, nature of toxic effects, available 
information concerning the cumulative effects of the pesticide chemical 
and other substances with a common mechanism of toxicity, and available 
information concerning aggregate exposure levels to the pesticide 
chemical and other related substances, among others.
    EPA establishes exemptions from the requirement of a tolerance only 
in those cases where it can be clearly demonstrated that the risks from 
aggregate exposure to pesticide chemical residues under reasonably 
foreseeable circumstances will pose no harm to human health. In order 
to determine the risks from aggregate exposure to pesticide inert 
ingredients, the Agency considers the toxicity of the inert in 
conjunction with possible exposure to residues of the inert ingredient 
through food, drinking water, and through other exposures that occur as 
a result of pesticide use in residential settings. If EPA is able to 
determine that a finite tolerance is not necessary to ensure that there 
is a reasonable certainty that no harm will result from aggregate 
exposure to the inert ingredient, an exemption from the requirement of 
a tolerance may be established.
    Consistent with FFDCA section 408(c)(2)(A), and the factors 
specified in FFDCA section 408(c)(2)(B), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for paraffin waxes including 
exposure resulting from the exemption established by this action. EPA's 
assessment of exposures and risks associated with paraffin waxes 
follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered their 
validity, completeness, and reliability as well as the relationship of 
the results of the studies to human risk. EPA has also considered 
available information concerning the variability of the sensitivities 
of major identifiable subgroups of consumers, including infants and 
children. Specific information on the studies received and the nature 
of the adverse effects caused by paraffin waxes as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies are discussed in this 
unit.
    Paraffin waxes exhibit low levels of acute toxicity via the oral, 
and dermal routes of exposure and they are anticipated to have low 
acute toxicity via the inhalation route. Paraffin waxes are non-
irritating to the eye or skin, and they are not dermal sensitizers.
    The repeated-dose toxicity for paraffin waxes is low. No adverse 
effects were observed in a 90-day oral rat study or in a developmental 
toxicity study in rats up to the limit dose. No acceptable oral chronic 
or carcinogenicity studies are available for paraffin waxes. However, 
there is low concern for genotoxicity or mutagenicity based on negative 
results in mammalian and bacterial genotoxicity tests. No evidence of 
neurotoxicity was observed in the neurotoxicity screening performed in 
the 90-day oral rat study and no evidence of immunotoxicity was seen in 
the available studies.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/overview-risk-assessment-pesticide-program.
    The hazard profile of paraffin waxes is adequately defined. 
Overall, paraffin waxes are of low acute, subchronic, and 
developmental/reproductive toxicity. No systemic toxicity is observed 
up to 1,000 mg/kg/day. Since signs of toxicity were not observed, no 
toxicological endpoints of concern or PODs were identified. Therefore, 
a qualitative risk

[[Page 16381]]

assessment for paraffin waxes can be performed.

C. Exposure Assessment

    1. Dietary exposure. In evaluating dietary exposure to paraffin 
waxes, EPA considered exposure under the proposed exemption from the 
requirement of a tolerance. EPA assessed dietary exposures from 
paraffin waxes in food and drinking water as follows:
    Dietary exposure (food and drinking water) to paraffin waxes may 
occur from foods containing these inert ingredients and from non-
pesticidal uses (e.g., cosmetics and personal care). However, no 
toxicological endpoints of concern were selected, and therefore, a 
quantitative dietary exposure assessment for paraffin waxes was not 
conducted.
    2. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., for lawn and garden pest control, indoor pest control, 
termiticides, and flea and tick control on pets). Although the current 
and proposed uses of paraffin waxes can result in residential 
exposures, no toxicological endpoints were selected, and therefore, it 
is not necessary to conduct a quantitative assessment of residential 
exposures and risks.
    3. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when 
considering whether to establish, modify, or revoke a tolerance, the 
Agency consider ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.''
    Based on the lack of toxicity in the available database, EPA has 
not found paraffin waxes to share a common mechanism of toxicity with 
any other substances, and paraffin waxes do not appear to produce a 
toxic metabolite produced by other substances. For the purposes of this 
tolerance exemption, therefore, EPA has assumed that the paraffin waxes 
in this petition do not have a common mechanism of toxicity with other 
substances. For information regarding EPA's efforts to determine which 
chemicals have a common mechanism of toxicity and to evaluate the 
cumulative effects of such chemicals, see EPA's website at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

D. Additional Safety Factor for the Protection of Infants and Children

    Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an 
additional tenfold (10X) margin of safety for infants and children in 
the case of threshold effects to account for prenatal and postnatal 
toxicity and the completeness of the database on toxicity and exposure 
unless EPA determines based on reliable data that a different margin of 
safety will be safe for infants and children. This additional margin of 
safety is commonly referred to as the Food Quality Protection Act 
(FQPA) Safety Factor (SF). In applying this provision, EPA either 
retains the default value of 10X, or uses a different additional safety 
factor when reliable data available to EPA support the choice of a 
different factor.
    Based on an assessment of paraffin waxes, EPA has concluded that 
there are no toxicological endpoints of concern for the U.S. 
population, including infants and children. Because there are no 
threshold effects associated with paraffin waxes, EPA conducted a 
qualitative assessment. As part of that assessment, the Agency did not 
use safety factors for assessing risk, and no additional safety factor 
is needed for assessing risk to infants and children.

E. Aggregate Risks and Determination of Safety

    Because no toxicological endpoints of concern were identified, EPA 
concludes that there is a reasonable certainty that no harm will result 
to the general population, or to infants and children from aggregate 
exposure to paraffin wax residues.

V. Other Considerations

Analytical Enforcement Methodology

    An analytical method is not required for enforcement purposes since 
the Agency is establishing an exemption from the requirement of a 
tolerance without any numerical limitation.

VI. Conclusions

    Therefore, an exemption from the requirement of a tolerance is 
established for residues of paraffin waxes, paraffin waxes and 
hydrocarbon waxes (CAS Reg. No. 8002-74-2); carboxypolymethylene resin 
(CAS Reg. No. 68153-22-0); and paraffin waxes and hydrocarbon, 
oxidized, lithium salts (CAS Reg. No. 68649-48-9) when used as inert 
ingredients (flow aid, surface protectant, binder, carrier, coating 
agent or adjuvant) in pesticide formulations applied to growing crops 
and raw agricultural commodities pre- and post-harvest under 40 CFR 
180.910, applied in/on animals under 40 CFR 180.930, and in 
antimicrobial formulations applied to food-contact surfaces in public 
eating places, dairy-processing equipment, and food-processing 
equipment and utensils under 40 CFR 180.940(a).

VII. Statutory and Executive Order Reviews

    This action establishes exemptions from the requirement of a 
tolerance under FFDCA section 408(d) in response to a petition 
submitted to the Agency. The Office of Management and Budget (OMB) has 
exempted these types of actions from review under Executive Order 
12866, entitled ``Regulatory Planning and Review'' (58 FR 51735, 
October 4, 1993). Because this action has been exempted from review 
under Executive Order 12866, this action is not subject to Executive 
Order 13211, entitled ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 
28355, May 22, 2001) or Executive Order 13045, entitled ``Protection of 
Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997). This action does not contain any information 
collections subject to OMB approval under the Paperwork Reduction Act 
(PRA) (44 U.S.C. 3501 et seq.), nor does it require any special 
considerations under Executive Order 12898, entitled ``Federal Actions 
to Address Environmental Justice in Minority Populations and Low-Income 
Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the exemptions in 
this final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.), do not apply.
    This action directly regulates growers, food processors, food 
handlers, and food retailers, not States or Tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
Tribal Governments, on the relationship between the National Government 
and the States or Tribal Governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian Tribes. Thus, the Agency has 
determined that Executive Order 13132,

[[Page 16382]]

entitled ``Federalism'' (64 FR 43255, August 10, 1999) and Executive 
Order 13175, entitled ``Consultation and Coordination with Indian 
Tribal Governments'' (65 FR 67249, November 9, 2000) do not apply to 
this action. In addition, this action does not impose any enforceable 
duty or contain any unfunded mandate as described under Title II of the 
Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.).
    This action does not involve any technical standards that would 
require Agency consideration of voluntary consensus standards pursuant 
to section 12(d) of the National Technology Transfer and Advancement 
Act (NTTAA) (15 U.S.C. 272 note).

VIII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA will submit a report containing this rule and other required 
information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the United States prior to publication of 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
